Tiny Tarrasque
Tiny monstrosity (character sheet), chaotic helpful
Your turn shouldn't wait for your phone. The fastest character sheet at the table: one tap to roll, rest or cast, with no signal and no account.
The hoard grows.

No Account. Your characters live on your phone. It never asks you to log in, and you can export a backup anytime.
Explain Number. Long-press any number to see where it comes from, so nobody argues with the DM about a plus seven.
Does the Math. Terry adds it up. You do the monster slaying, the dungeon delving and the dragon seducing.
Legendary Actions
The sheet can take these actions on your turn, each in one tap.
Roll. Attack and damage together, crits included.
Rest. Spend hit dice and get Second Wind back.
Cast. Spell slots tick themselves off.
Lair Actions
When does the beta open?
13 November 2026, on Android and on the web. iPhone: tell us on sign-up. If 100 iPhone people join the list, we open an iOS beta too.
Is it free?
Yes. The app is free to use with every open-licence rule. You only pay if you want extras: cloud sync, party tools and other premium features, coming in 2027.
Which rules does it support?
The 2024 fifth edition rules from the System Reference Document 5.2.1. Levels 6 to 20 follow soon after the beta opens. A second game system comes in 2027, and you get to vote on which one.
Can I add my own rules and homebrew?
Yes. Make, import and share your own homebrew for free; the app ships none. The homebrew editor is in beta: create subclasses, spells, items and feats in the app, or import your own rules from a file. The app ships with open-licence content only, no homebrew.
Where does my data live?
On your phone. There's no account in the beta, and you can export your characters as a backup file anytime.
Who's building it?
I'm Nick, a software engineer in Helsinki who plays all kinds of tabletop RPGs. I'm building this alone and in public because my own table kept stalling on "is it plus five or plus seven?". Terry, a very small tarrasque, supervises. Follow the build at @tinytarrasque on the links below.
